logger
Sink for the library's own diagnostics — a failed delivery, or an event dropped for failing validator. Defaults to printing to the console (the historical behavior); set your own to route them into your app's logging framework (Logcat, os_log, Timber) or to silence them. See AutographLogger. This routes only the diagnostics of a constructed tracker; a pre-provider warning (compose's MissingTracker) or a storage-fallback notice logged before a tracker exists still goes to the console, since there is no configured logger yet at that point.
